Pseudoptosis (bottoming out) is a well-observed phenomenon occurring after all types of breast reduction surgery. The authors' team previously reported the use of three-dimensional (3D) imaging to demonstrate that significant morphologic changes occur in the breast during the first year after short-scar medial pedicle breast reduction. This study extended this evaluation to postoperative year 3.
Patients undergoing short-scar medial pedicle breast reduction had 3D photographs taken using the Canfield Vectra 3-pod system or the Konica Minolta V910 during postoperative follow-up visits at 1 month, 1 year, 2 years, and 3 years. Patients were assessed for pseudoptosis and breast morphologic changes using the 3D-based measurements.
During the 3 year period, 10 patients completed the study. The total breast volume decreased significantly during the first postoperative year by 20.6% (P < 0.05). No change in volume occurred during postoperative years 2 and 3 (P > 0.05). Pseudoptosis was documented in the first postoperative year by a 6% migration of breast tissue from the upper pole to the lower pole of the breast (P < 0.05), without significant change noted during the next 2 postoperative years (P > 0.05). This redistribution of the breast parenchyma correlated with a decrease in breast anteroposterior projection of 10.6 mm (P < 0.05) during the same period, with an insignificant change during postoperative years 2 and 3. During the first postoperative year, 3D comparative analysis recorded a 4.4-mm difference in the 3D topography (P < 0.05) and no further changes thereafter. The angle of breast projection showed a significant decrease of 17% (P < 0.05) in the first postoperative year and no change in subsequent years.
Three-dimensional photography is a useful tool enabling the plastic surgeon to monitor the postoperative changes in breast morphology objectively. This study provides quantifiable data demonstrating that pseudoptosis and tissue redistribution are limited to the initial postoperative year for patients undergoing short-scar medial pedicle breast reduction. The kinetic change in the breasts during postoperative years 2 and 3 appears to be minimal. Studies comparing the changes in morphology over time with different techniques of breast reduction are underway.
假性脱垂（最低点）是一种在所有类型的乳房缩小手术后都会观察到的现象。作者团队此前曾报道使用三维（3D）成像来证明，在短瘢痕内侧蒂乳房缩小术后的第一年，乳房会发生显著的形态变化。本研究将这一评估扩展到术后 3 年。
接受短瘢痕内侧蒂乳房缩小术的患者在术后 1 个月、1 年、2 年和 3 年的随访中，使用 Canfield Vectra 3 足系统或 Konica Minolta V910 拍摄 3D 照片。使用基于 3D 的测量值评估假性脱垂和乳房形态变化。
在 3 年期间，10 名患者完成了研究。术后第一年，总乳房体积显著下降 20.6%（P<0.05）。术后第 2 年和第 3 年，体积无变化（P>0.05）。在术后第一年，通过乳房组织从乳房上极向乳房下极迁移 6%，记录到假性脱垂（P<0.05），在接下来的 2 年中没有明显变化（P>0.05）。在此期间，乳房实质的这种再分布与乳房前后向投影减少 10.6mm 相关（P<0.05），在术后第 2 年和第 3 年无明显变化。在术后第一年，3D 比较分析记录了 3D topography 上 4.4mm 的差异（P<0.05），此后没有进一步变化。乳房投影角度在术后第一年显著下降 17%（P<0.05），随后几年无变化。
三维摄影是一种有用的工具，使整形外科医生能够客观地监测乳房形态的术后变化。本研究提供了可量化的数据，证明在接受短瘢痕内侧蒂乳房缩小术的患者中，假性脱垂和组织再分布仅限于术后初始 1 年。在术后第 2 年和第 3 年，乳房的动态变化似乎很小。正在进行比较不同乳房缩小技术随时间变化的形态变化的研究。
